From one fat guy to another, take Joe's advice and head to a dealer and see what not only fits, but what speaks to you. That doesn't mean you have to buy from a dealer, it's just a chance to see what fits.
BTW, dieting sucks, my pants no longer fit and I still hate the treadmill, but damned if I don't feel better, especially after seeing Candyman's answer. LoL
I want to die in my sleep like my grandfather, not yelling and screaming like the passengers in his car.
When I was a child, I thought nap time was punishment.
Now it's like a mini-vacation.
What doesn't kill you sometimes make you stronger,
and sometimes it just pisses you off!!
